Patented Mar. 15, 1938 UNITED STATES -PATEINT- OFFlCE TABULATING MACHINE Application July "2, 1934, Serial No. 734.124 reclaims. (Cl.2$61.9)

This invention relates to improvements in electric accounting machines and particularly to machines utilized in the preparation of statements or bills such as issued by public utility 5 systems.

The principal object of the invention is to improve the interrelation between the various units of the. machine to the end that the efficiency and reliability of the system may thereby be increased.

' utility systemsare usually comprised of several separate portions such as the statement proper, the cashiers coupon, and a collection stub. Each of these sections receives common information, such as the separate values of the various items of service together withthe total payable. These items are entered on the bill under control of perforated record cards which are analyzed electrically and the information in a particular field controls the duplicate printing in each of the several portions of the bill.

In order-to insure that items which are to appear in all portions of the bill will be correctly printed, the machine is provided with checking r, mechanism associated with the type bars which will cause the machine to stop, if the setting of the bars is such that the same amount will not appear in each portion of the bill. The checking mechanism also serves to control the entry of n' the common information into an accumulator which accumulates the total amount of the bill. The checking mechanism functions while the machine is listing, to control the printing of common information as obtained directly from the analyzedrecord cards. With the provision of this checking mechanism, it is fairly assured that all items entered into an accumulator-are in correspondence with the items printed and that the same items are printed in the different portions of the bill. l

After the various individual items have been listed on the bill and each amount has been separately entered into the total accumulatonthe machine enters into a total taking cycle of operations during which the amount standing in the total accumulator controls the setting of the type bars to print the total in each of the several sections. This setting is again checked for agreement'in the several positions and, if agreement further grand or froute total. This trans ferred total will therefore only be entered into the grand" totalizer, if and when the amount to be transferred is definitely and correctly set up 'on Statements as prepared for use in public is found, the total will also be transferred to a the several groups of type bars which are to print the same on the bill. Thus, each entry into either the bill total accumulator or grand total accumulator is definitely controlled by the setting of the type bars and the entries must necessarily correspond with the information printed.

In the event of any lack of agreement during any. type bar setting operation, the machine will stop and a distinctive signal lamp will be illumihated to apprize the operator that some disagreement is present in the type bar settings which might be due to some mechanical or electrical reason.

After the printing of a total upon a bill, the bill total accumulator is cleared and the machine proceeds to prepare the next bill. After all the bills for a given route have been prepared, the machine automatically stops and a signal lamp is illuminated to call thisto the operators attention. At this time, the total in the grand total accumulator may be noted and a comparison made with a known total with which it should conform.

If these are in agreement, it is reasonably certain that all the bills for that particular route have been properly prepared in all details and that no errors are present in any of them.

For each bill to be prepared thereis one'or more cards depending upon the numb r of service items to be billed; for example, there may be a gas card, an electric" card, and a merchandise card, arranged in the order stated. On either the gas or electric card may appear a tax charge or an arrears charge or both. If such tax or arrears amount is present on one of the cards, the machine automatically performs extra cycles of operation to cause the printing of the tax and the arrears amounts on separate lines of the bill before proceeding with the analysis .of the next succeeding card.

Various other objects and advantages of the invention will be obvious from the following particular description of one form of mechanism embodying the invention or from an inspection of the accompanying drawings; and the invention 7 also constitutes certain new and novel features Fig. 3 is a central section of the printing mechanism.

The machine to which the features of the present invention are applied is similar to that shown in the copending application of C. D. Lake and G. F. Daly, Serial No. 672,388, filed May 23, 1933, now Patent No.1,976,617. This copending application illustrates and explains in more extensive detailthe manner of organization and mode of operation of the various units of a well known type of tabulating machine. In the present application, these mechanisms will be explained in only as much detail as will be necessary to point out the manner in which the objects of the present invention may be realized.

Before setting forth' the general operation of the machine, the various mechanical units will be described and their relationship pointed out thereafter.

Card feeding mechanism The card feeding mechanism shown in Fig. is exactly similar to that shown and described in the application referred to except that provision is made in the form of a clutching device for interrupting the card feeding. operations without stopping the accumulating drive mechanism. The analyzing brushes are indicated atUB and LB and the record cards R are successively advanced by picker 9 to pairs offeed rollers l0 which serve to advance the cards past the upper and lower brushes U13 and LB in succession. The shafts upon which rollers i II are mounted are provided with gears at their extremities, arranged as shown in Fig. 1 for operation by a main driving gear II which is freely mounted upon a shaft 8 and which has connection with an arm I5 through a sleeve 1. Arm |5 carries spring-pressed clutching dog l6 normally held in the position shown by an armature latch H which is adapted to be controlled by the clutch magnet l8. Between gear ii and arm l5 are a gear l3 and a clutch driving disk l4 freely rotatable upon the sleeve I. Gear I3 has gear connection generally designated I2 with the pulley shaft 6 which is in operation as long as the main driving motor is operative.

I6 into engagement with disk. and the card feeding mechanism will cause cards to be advanced past the brushes U13 and LB and feeding operations will continue as long as magnet l8 remains energized.

During transferring and total taking cycles of operation, magnet i8 is deenergized and card feeding will, of course, not take placeduring such cycles.

Printing mechanism The printing mechanism is shown in Fig. 3

. the toe of stop pawl 36.

Energization of magnet I8 will trip dog where type bars 20 are carried by crosshead 2| which is slidable vertically on rods 22. Springpressed arms 23 pivoted to the crosshead at 24 have their free ends abutting the lower extremity of the type bars so that as the crosshead moves upwardly, the type bars are urged in the same direction. The reciprocatingmovement of the crosshead is controlled from shaft I9, which as shown in Fig. l is continually driven from the main operating shaft 6. Shaft l9 has secured thereto clutch driving element 25 notched to cooperate with a clutching dog 26 carried by and pivoted to listing cam 21. Clutch releasing arm 28 cooperates with dog 26 to hold the parts in the position shown when magnet 29 is deenergized. Energization of magnet 29 will rock arm 28 in a counterclockwise direction'releasing dog 26 for engagement with element 25 whereupon thev listing cam will rotate with shaft l9 and through follower arm 30 will oscillate shaft 3|.

Secured to shaft 3| are arms 32 whose free ends have link connection tothe crosshead 2| which will thereby be reciprocated once for each revolution of the listing cam. As the type bars move upwardly, the type elements 33 will suecessively pass its printing position opposite platen 34 and ratchet teeth 35 will successively pass Energization of printing magnet 31 will trip latch 38, permitting stop pawl 36 to engage one of the ratchet teeth 35 thus positioning the corresponding type element opposite the platen.

An auxiliary crosshead 39 is provided which is slidable upon rods 40; The crosshead 39 is link connected with a lever 4| pivoted at 42 and having its shorter arm connected by a link 43 to an.

arm 44 secured uponshaft 3|. With this arrangement the cross head 39 moves upwardly in unison with the crosshead 2|. Carried by crosshead 39 are adjustable camming elements 45, one for each type bar. Each element is adapted to cooperate with an interposer 46 pivoted to and depending from arm 23. The operation of the mechanism is such that as the crossheads move upwardly the parts maintain the same'relatlve positions theyoccupy in Fig. 3. Upon the energization of magnet 31, however, and the consequent interruption of further upward movement of type bar 20, the lower extremity of the bar will become a fulcrum for the free end of arm 23. The pivot point 24 of arm 23 will, of course, continue its upward movement with the crosshead 2| so that the interposer 46 will now move upwardly at a greatly reduced rate.

The camming element 45 moving upwardly with crosshead 39 will force the free end of interposer 46 toward the left momentarily as the camming portion of element 45 passes the cam ming surface of the interposer. In alignment with interposer 46 is a link 41 carried by a pair of bell cranks'48 and 49 which are connected for parallel movement by a link 50. Movement of interposer 46 toward the left will cause a corresponding movement of associated link 41 and the extending nose 5| thereof will cause closure of a pair of contacts 52. For convenience in construction, alternate links 41 have the extensions 5| at opposite extremities and the. related contacts '52 are similarly staggered.

There is but a single pair of contacts 52 ass ciated with each of the type bars. In Fig. 3 there are two contacts 52, one of which is asso ciated with the type bar shown .and the other is associated with the next adjacent type bar. As

the contact, blades are wider than the spacing between adjacent type bars, it has been inconvenient to place the contacts side by side and they have accordingly been staggered. The contacts associated with the even number type bars are placed at the upper level and their operating links 41 have only the upper nose 5i. The contacts associated with the odd numbertype bars 'are placed at the lower level and their operating links 41 have only the lower nose 5|.

Briefly then, the energization of the printing magnet 31 will interrupt the type bar 20 with a printing element in position. Immediately following the interruption of the type bar movement, the resultant relative movement between interposer 46 and camming element will cause momentary closure of the associated pair of contacts 52. These contacts are utilized to control the entry into the accumulator of the value set up on the type bar in the manner to be pres ently explained.

Accumulating mechanism The adding mechanism is entirely similar to that shown and described in the application referred to and the description thereof will accordingly be limited to a brief explanation of its manner of operation. The accumulator drive shaft 53 (Fig. 6) is geared directly tothe pulley shaft 6 of Fig. i so that it is in operation as long as the driving motor of the machine functions and the driving ratio is such that shaft makes one revolution for each card feeding cycle of the machine. Shaft 53 has slidably mounted thereon but keyed for rotation therewith a clutch element 54, one for each denominational order of the accumulator. The element 5 is provided with a groove in which fits the short arm of a lever 55 which is pivoted as shown and provided with a block 56 normally held as in 6 by armature latch 51 of adding magnet 58. A leaf spring 59 bears against the extremity of the longer arm of lever 55 and moves the same in a counterclockwise direction upon release of block 56 by armature 51. This movement will bring clutching member 54 into engagementwith cooperating teeth 60 integral with a gear 60 loosely mounted on shaft 53. Gear 5i, when thus coupled to shaft 53, will rotate a gear which meshes therewithand will displace the accumulator index wheel 53. I

The rearward extremity of member 55 is adapted to be engaged by a finger t l toward the end of the cycle for the purpose of disengaging the clutch element 54 from teeth 50 and re-latching block-58 on armature 5i.

Briefly summarizing the adding operation, the

magnet 58 may be energized at various points in the cycle of the machine, depending upon the location of a perforation in the column of a record card analyzed by the lower brushes LB.

This energization may take place in response to a perforation in any of the index point positions from 9 to l, inclusive. A perforation in the 9 index point position will trip the clutch element 54 nine steps before finger 55 is operated to declutch it and a perforation in the l index point position will trip the clutch element 56 one "step before it isdeclutched by the finger fi l.

I revolution and the 1 hole will move it of a revolution. I

The energization of magnet 58 is controlled by the closure of the contacts 52 associated with they printing mechanism. The manner in which the circuits are completed will be set forth in connection with the explanation of the circuit diagram.

Read-out mechanism Also driven by gear ti (Fig. 6) is a gear 65. Since the ratio of gears and 62 is 2:1. the former will turn through a halfvrevo-lution for each revolution of the latter. Carried by and insulated from gear 65 is a pair of electrically connected brushes '65, one of which cooperates successively with ten conducting segments 61 while the other cooperates with an arcuate conducting strip 63.

ihe relationship of the partsis such that when the index wheel 63 is inits zero position, one of the brushes G6 is in contact with the zero segment Eli and the other brush is in contact with the strip 5%, thus forming an electrical connection between the two. If the wheel 63 is displaced to indicate, say 8, then one of the brushes will be in contact with the 8, segment 51" and the other brush will be in contact with the arcuate strip The positioning of the brushes fit provides a convenient electrical read-out mechanism for controlling total transferring and total printing operations and the electrical circuits involved in these functions Will be more fully explained in connection with the circuit diagram.

Accumulator resetting mechanism The shaft (Fig. d).upon' which the index wheels 63 of an accumulator are loosely mounted is slotted for cooperation with spring-pressed pawls (not shown) pivoted upon and carried by the individual index wheels in such manner that counterclockwise rotation of shaft 55 will engage and drive the index wheels 53 forwardly to zero position during a single revolution of shaft @9- Referring to fig. 2, shaft 59 carries a gear iii at its extremity which is in engagement with gear it mounted upon reset shaft l2. Gear it, of which there is one for each accumulator, may be selectively coupled to the resetting shaft lit in the well known manner 'niore fullyexplained in the application above referred to. At the ex trernity of shaft i2 is a gear it (see also 5) which is adapted to be driven by an intermediate gear M which is secured to shaft it. Also fixed to shaft 0 is an arm which carries springpressed clutch dog 7? normally held in the pcsi= tion shown in 2 by a latching arm it? sup= ported by armature shaft is of magnet ture Eli].

hnergization of magnet iii will release dog it for engagement with clutch driving element 82. Element 82 meshes with a gear 86 se ured upon constantly running shaft Ml. With th's arrangement drive element 82 is in constant -otation and when- "ever it is desired to effect resetting of the accumulators, magnet iii is energized to provide a connection between the element 82 and the resetting shaft Resetting is usually an accompaniment of total taking and by virtue of the intermittent gear connection occurs during the latter part of a total taking cycle.

Circuit controlling devices '1 in Fig. 4 is shown. a so-called emitter which cooperates with the read-out devices of the accumulator for total printing or total transferring operations. Carried by a stud 85 coaxially with is integral with a gear 83 which brushes 96, one of which contacts with conducting segments 91 while the other wipes over a common arcuate conducting strip 98. The brushes 86 are carried by a gear 89 driven through an idler 90 from a gear 9| carried by constantly running shaft i9. The emitter used for controlling total printing operations is'timed so that a brush 96 successively contacts with each of the segments 81 as the corresponding type elements 33 of Fig. 3 approach printing position opposite platen 34. The emitter used for controlling total transferring operations is timed so that one of its brushes I5 successively contacts with each of the segments 91 at times appropriate to the entry of corresponding digits into the accumulators.

In Fig. 3 are shown a plurality of cam con-. trolled contacts whose operation is controlled by cams carried by a shaft 92 driven from shaft 15. The contacts are prefixed P" to indicate that they function only during totaltaklng and resetting operations. Similar cam controlled contact devices prefixed with the letter L are carried by. or may be driven from the shaft I9 and these are in constant operation as long as the driving motor functions.

In Fig. 1 is shown a shaft 93 which is driven from the gears of the card feeding mechanism and. rotates only when cards are being advanced. Controlled by suitable cams on shaft 93 are con-- tact devices, each of which is designated by the letter F indicating that they are associated with the feeding mechanism and operative only when the feeding mechanism functions.

All these cam contact devices are indicated in the timing diagram (Fig. '7) where their relative timing may be observed.

General explanation of the circuit diagram The wiring diagram of theijelectric circuits is shown in Figs. 8, 8a and 8b wherein the various cam controlled contact devices are diagrammatically shown. and suitably labelled F, L or P for identification as just explained. The exact timing of these contact devices is shown in Fig. 'lto which reference may be made for the-actual time in the cycle of operation during which they function. Due to the numerous interlocking relays employed in the present arrangement, it has not been advisable in all instances to show relay magnets and their associated contacts in close proximity to one another; I

For purposes of clarity in the wiring arrangement, the relay contact points are shown in the circuits which they control and their relay magnets are repeated. adjacent thereto. Further than this, the contacts are designated with the same reference numeral as their controlling magnet, followed by a lower case letter.

General operationr-The general operation of the machine will first be outlined with particular reference to Figs. 9 and. 10. The record card R is provided with data fields labelled as shown, which are to control the printing by type bars 29 and certain of which will control the entry A of data into the accumulators l-5 indicated below the row of type bars.

All of the card fields from which printing is to be controlled are connected directly to the from the direct listing fields are branched to effect the same entry into more than one section of the type bars; for example, the consumption,

field enters its data in two places. In such case. these positions of the type bars are provided with the checking contacts 52 to insure that printing will actually be the same in the related positions.

The gross bill and net bill" fields are connected for entry into three sections of the type bars through a connection indicated at 91 as follows: from the card fields through connection 91, relay contacts R99a, R99a, and Rlilila in series, connection H, to the appropriate type bars 29, as indicated by vertical lines extending upwardly from connection Iill. If the data is correctly printed in the several positions on the bill, the same information is entered in ACC#I through connections 98 which, under control of the type bar contacts 52, transfer the data through connection 99, relay contacts Rl02a, to ACC#I. The timing of ACC#I is adjusted to take account of the time delay between the analysis of the card field and the eventual entry into the accumulator.

If a record card contains tax or arrears perforations, a cycle of operations follows an initial entering cycle, during which following cycle the data standing in ACC#4 is printed and transferred to ACC#i, and during a succeeding cycle the data in ACC#5 is similarly printed and transferred. During the tax" transfer cycle the contacts R99a are open and contacts R99!) are closed and the data is read from the upper or read-out section of ACC#4 through connection I03, contacts R991), contacts Rlilila, connection IN, to the gross and net bill" sections of A the type bars and from there, if the-duplicate printing is correct, through the checking contacts 52 and connections 96 to ACC#i. During the"arrears" transfer cycle, contacts Riilila are open and Rliliib closed so that the transfer is similarly effected from the read-out section of ACC#5 through connection I94, contacts Rlliflb, connection IM, to the type bars, and from thence to ACCiH.

After all the record cards for a particular account or folio number have been analyzed, the machine will enter into a total taking cycle of operations during which contacts R99a and RlMa are open so that the total in ACC#| may be transferred from the read-out section thereof through connection I05, contacts R981), now closed, contacts R9911, Rlfliia, connection IN, to the several sections of the type bars and, again. if the printing is the same in all positions, through connections 96, contacts R1921), to ACC#2. At the completion of this total taking cycle, ACC#i is cleared but the data is retained in ACC#2 which will receive all totals and at the completion of all tabulating operations will show what is termed the route total which may be compared with a known value. After all the record cards for a particular route" have been analyzed the machine will stop.

Initial reset cycle.In the lower part of Fig. 8

is shown the usual group control mechanism,

generally designated (30, and as is usual in tabulating machines, it is first necessary to set up the major and minor holding relays R42 and R48 before the machine can be started. This is eifected by depression of the reset key to close contacts H9, thereby completing a circuit from right side ofline Ill, wire H2, contacts H0, re-

lay contacts R99c, Rliiiic, relay coil R99, to left side of line H9. Energization of magnet R39 will close its contacts Rlilain the upper part of incidentally,

iii)

/ Fig. 8 which will thereupon complete a circuit from right side of line H I, stop key contacts I I4, contacts R49a, wire H5, contacts Ra, relay magnet R25, -contacts H6, main drive clutch magnets III, to line H3. Energization of magnets II'I will cause coupling of the driving motor to the pulley shaft 5, mentioned above, and will, cause opening of contacts 0 l6 whereupon relay RI will be included in the series circuit through magnet I I'I and/will close its contacts Rla to complete the circuit through motor TM.

Contacts R25a provide a holding circuit which is traceable from the contacts through cam contacts LI and wire H2 to line III. LI open toward the end of each cycle, and at such time, the circuit through magnet R25 is maintained through either contacts UCLa, or contacts LCLa which are in series with contacts REM, R4 Ia, R4961, and'stop key contacts M.

The manner in which one or more of these contacts in the holding circuit may be opened to interrupt the same will be explained hereinafter. When the machine is set for automatic resetting, following total taking operations, switch it? is closed to short-circuit contacts R4911.

The relay magnet R39, energized by depression of the reset key will close a second pair of contact points R3622 for completing a circuit from line ill, wire H2, cam contacts L2, contacts R3572, reset magnet at, to line H3.

As explained in the mechanical description, energization of magnet BI will efiect resetting of the accumulators and will cause a cycle of operation of the P cam. contacts of which contacts PT! (the lower part of Fig. 8) close to set up the minor control circuit and contacts Pt operate to set up the major control circuit. The detailed manner in which the group control mechanism GO functions to control the operation of the machine is well known in the art and fully set forth in the Patent No. 1,976,617 above referred to so that such detailed description will be unnecessary here. Suffice it to say that upon a change in the minor group classification perforations which in the present case relate to folio-number, relay magnets R33, R will become deenergized and a change in the major group classification perforations which in the present case relate to the route number, will cause deenergization of relay magnet R42 along with R43 and act.

Starting circuit-With the group control set up, that is, with magnets R42, R43, and RM energized, and the accumulators cleared, the machine is in readiness to feed cards and analyze the data thereon. Depression'of start key and closure of contacts H9 will complete a circuit from line IIi,wire H2, c'ontacts H9, relay magnet R33, contacts R49b, relay magnet R32, to line M3. The contact points R33a are in parallel with the contacts R300. and will complete the following circuit through the driving clutch magnet and cause operation of the motor TM. From line H3, magnet Ill, relay RI, magnet R25, contacts R33a, wire H5, contacts R49a and H4 to line ill.

Relay magnet R32 is provided with a pair or contacts R32a which are adapted on closure to complete a circuit to the card feed clutch control relay magnet R39. This circuit is traceable from line I I3, magnet R39, contacts R3211, stop key contacts Illa (operable concurrently with the contacts H4),'contacts R430 of the minor control relay magnet R43 which are now closed, contacts RIIIIIg, R999, contacts P9, ,wire H2, to. line HI.

This circuit, it will be observed, can only be com- Cam contacts pleted when the group control relay magnet 43 is energized. Magnet R39 will close its points R390. to provide a holding circuit for the magnet and a second pair of points R3912 wired in series with the card feed clutch magnet I8 will energize the latter so that cards may commence to feed. The holding circuit for magnet R39 is traceable from line H3, magnet R39, contacts R39a, contacts LCLp, illa, R43c, RI99g, R999, P9, wire H2 to line Hi.

Card lever circuits.--As the cards are advanced' past the upper'set of analyzing brushes UB, the usual card lever contacts I29 are closed to complete a circuit. from line III, contacts I29, relay magnet R21, magnet UCL, wire I2l, to line I I3.

Ma'gnetUCL controls a number of contacts which are disposed in various circuits for controlling purposes. One of these contacts, for example UCLa pointed out above as being in the holding circuit of the motor drive clutch, will open to interrupt this circuit,iff cards fail to feed past'the upper brushes. Since the card lever contacts lit open between the successive cards, a

holding circuit is provided through contacts RZlaand cam contacts L5 which serve to maintain magnet UCL energized during the interval when contacts 029 are open. In a similar manner, the

'lower card lever contacts l22 cause energization of relay magnet R29 and lower card lever relay LCL and the contact points R290. cooperate with cam contacts L5 to provide a similar holding circuit.

Listing circuits-Toe circuit for the listing magnet 29 is completed from line ill, wire M2,

contacts L2,.Plt, list earn clutch magnet to line fill Through this circuit, magnet 29 is energized each cycle or" operation or the machine and the printing mechanism will function accordingly.

As the record cards advance past the lower brushes LR the entries made in the fields containing descriptive data are directly entered on the type bars as explained in connection with Fig. 9 and any data contained in the demand, tax or arrears fields enteredinto ACC#3, ACCiH,

and ACCt Ei, respectively. Entries in the bill fields will be printed on the bill directly and upon closure of contacts 52 will be thereupon entered printing magnet 3i and through plug connections 098 to similar printing magnets 31 in the appropriate positions for duplicate printing of the amount sensed. With the circuit just traced, the amount perforated in the selected card column will be printed in three places on the bill and as each type bar is interrupted, the associated pairs of contacts 52 will be closed at the same time if the bars are correctly positioned. The contacts 52 are shownin Fig. 8a and arranged in groups as shown. Assuming the three lowermost contacts to be associated with the three type bars positioned as just explained, their concurrent closurewill complete a circuit from right side of line i l l, through the emitter, generally designated I23, wire I24, the three lowermost contacts 52, .wire I25, enclosed in the cable 58 of ACC#I, to left side of line II3. As explained in the mechanical description, the contacts 52 close momentarily at the time the upward movement of the type bar is intercepted and unless the three associated type bars are intercepted at the same time, the last traced circuit will' not be completed and no entry will be made in the accumulator.

Error indicating circuits;--The circuit traced through contacts 52 in series has a parallel branch circuit extending from the contacts through the right hand coil of a double wound relay magnet R15 and through wire I26 to line II3 so that the relay becomes energized whenever there is correct duplication of the printing.

Energization of the relay will close associated pairs of contacts R15a and R15b, the-former providing a holding circuit for the relay which extends from line H3, through wire I26, left hand winding of relay R15, contacts R15a, wire I21, cam contacts L8, to right side of line III. This circuit is maintained until contacts L8 open near. the end of the cycle. Contacts R151) are wired in series with similar contacts associated with other groups of type bar positions so that if correct printingtakes place in all positions, all of the contacts R15b will be closed and a circuit will be completed therethrough extending from line III, through wire I28, contacts R151), relay magnet R36, to line I I3.

Relay magnet R36 is normally held energized through a circuit extending from line II3, magnet R36, cam contacts LIO to right side of line. Near the end of each card feeding and analyzing cycle, cam contacts LIO open momentarily and if there has been agreement in: all printing positions, the circuit through the relay will be maintained through the series contacts R15b as traced. If one of the contacts R15b fails to close, the relay circuit will be vdeenergized.

Referring now to Fig. 8 the deenergization of relay magnet R33. will permit closure of its contacts R36a thereby establishing a circuit from right side of line III, through wire II2, contacts R3312, contacts R360, relay magnet R35 to line II3. A parallel circuit will also flow from contacts P5 close near the end of the cycle, a circuit is established from line I I3, through relay magnets R38, R31, contacts P5, switch I30, contacts R3541, contacts 33b, wire I 12,, to line I I I. Magnet R31 closes its contacts R3121. to provide a holding circuit for the relays through cam contacts L4. Relay magnet R38 opens its contacts 38a which are in the main clutch'magnet circuit at the upper part of Fig. 8, so that the machine will stop at the end of the cycle.

It will be apparent from the foregoing that the lamp I29 .will be illuminatedat the-time an error in printing is detected but the'machine will nevertheless complete the preparation of the bill and will then come to a stop with the lamp I29 indicating the reason'for stopping. As will be."

pointed out hereinafter, the machine may automatically stop at this time for other reasons and the lamp I29 serves to identify the stopping as shown, contacts RIII2b, accumulator magnet.

action as being due to the non-conformity of the duplicate printing.

Thus far we have seen how the data perforated in the three fields of the card, namely, the "bill" field, the "tax and the arrears fields, are entered into ACC#I, ACC#4 and ACC#5, respectively and the amount of the bill printed. This cycle of operations takes place for each of the cards of the group having the same folio number. 1

Tax transfer cycle setup-Referring now to Fig. 8, a plug socket I3I is provided from which a plug connection is made to the lower brush LB associated with column 22 of the record card R.

. Record cards containing a perforation in the index point position of this column are thereby identified as containing tax data, which is to be cross added with the other amounts on the bill. I

The analysis of this X perforation as it passes the lower brushes will complete circuits to prepare the machine for a transferring operation at the end of'theanalysis of the group of cards relating to the particular account which have tax or "arrears items thereon. The initial circuit extends from the right side of line I I I, lower card lever contacts I22, wire I32, cam contacts P2, circuit breakers I33, cam contacts FI, lower brush common, X22 perforation, plug connection such as I34, socket I3I, contacts F5, relay magnets R46 and R41 in parallel, wire I2I, to line H3. This circuit is held through contacts R46a extending from line III, through relay contacts R52a, contacts R46a, relay magnets R46 and R41, wire I2I, to line II3. pair of contacts R4111 which will set up a circuit upon completion of the analysis of the card group as will be explained later. A second pair of con tacts R41b will also be opened'at this time. Thus an X22 perforation in any of the cards of the group will energize relay magnet R41 which will thereafter remain energized to control the "tax amount transferring operations during later cycles. 7

Arrears transfer cycle setup.-An exactly similar set of circuits is completed to prepare the machine for transferring the arrears" amount. In

a this case, the socket I35 is provided which is plug Magnet R41 is adapted to close a connected to the lower brush LB which traverses column and an X perforation in this column will, through cam contacts F5, cause energization of relay magnet R45 whose contacts R45a provide a holding circuit and whose conrelay magnet R45 will have been similarly energized and its related pairs of contacts. also shifted.

-- --C1 cles 0/ operation Initiation of transferring operations.--In the following it will be assumed that the machine is to perform successive tax and arrears transferring operations upon the completion of the analysis of a group of cards and the various step involved in these operations are now to be explained.

It may be explained at this point that a group of cards relating to a particular account are arranged with service cards, such as gas and electricity cards, leading and any cards having data relating to merchandise placed at the end of the group. In order that the merchandise item appear as the last item on the bill (see Fig. 10) the machine is arranged to perform the tax and/or arrears transferring operations before the merchandise card is analyzed. The manner in which such analysis is suspended until transferring has been efiected will be explained hereinafter.

Record cards bearing data relating to merchandise have an X punching in column 54 and the upper brush traversing this column is connected to a plug socket I36 (Fig. 8a) and on the sensing of this X perforation, a circuit will be completed from line H3 (Fig. 8), cam contacts LII, LI2, upper brush common, X54 perforation, upper brush UByplug connection such as I31 (Fig. 8a), socket I38, cam contacts F4, relay magnet R55, wire I38, upper card lever relay contacts UCLb, to line III.

Relay magnet R55 closes its contacts R55a to provide a holding circuit through cam contacts Fllt'whose time of closure is the same as contacts F2 and F3 except that the point of opening of contacts F I 8 is slightly earlier in the cycle. Relay magnet R55 will close a second pair of contacts R55b so that near the end of the cycle, closure of cam contacts LI3 will complete a circuit from right side of line III, cam contacts LI3, contacts R55b. contacts R41a, relay magnet R99, wire I2I,- to line .II3. Magnet R99 will close its contacts R99d to provide a holding circuit through cam contacts LI1 and P8. A second pair of contacts R99g in the stop circuit of the machine opens to break the above traced holding circuit which extends through stop key contacts HM and includes relay magnet R39. The consequent deenergization of magnet R39 will cause opening of its contact points R39b in the card feed clutch magnet circuit so that card'feed clutch magnet I8 will therefore become deenergized and further card feeding suspended until transferring operations have taken place.

If the group of cards contains no merchandise card with the distinguishing X54 perforation, the same interruption of card feedingand energization of relay magnet R99 will be brought about under control of the group control mecha-' nism GC shown in the lower part of Fig. 8 which in the well known manner will cause deenergizat'ion of relay magnets 44 and 43. Magnet 43 will open its contacts R430 in series with the contacts R999 and will cause interruption of card feeding in the same manner. Deenergization of relay magnet R44 will permit closure may effect energization of relay magnet R99.

Tax transfer cycle.The machine is now prepared to transfer the tax amount from ACC#4 to ACC#I. This transferring is aigain controlled through the type bar contacts; that is, the data is read from the accumulator and entered upon the type bars, which, if properly set for duplicate printing, will effect the entry in ACC#I.

Referring now to Fig. 8b the amount standing in AC C#4 will be represented by the location of the various brush structures 88 which bridge the individual segments81 and common strips 88. The emitter shown in the lower portion of Fig. 8a will have its common strip 88 connected to the rlght side of line III through wire I39 see also Fig. 8), impulse distributors I83, contacts P2, wire I32, and lowercard lever contacts I22.

Impulses will thus be successively impressed upon the segments 81 through the brushes 88 in the order 9, 8, '1, etc., to transmit these impulses to all of the nine segments 81, all of the eight segments 61, and so on in succession. Wherever a segment is connected by a brush 88 to its related strip 88 the circuit will be completed as follows: Assuming that the brush 66 in the highest denominational order of the ACC#4 is set (as indicated in dotted outline) to bridge the 5 segment 81' and its strip 88, at the 5" time in the cycle, therefore, a circuit will be completed from line III, to common 88 of the emitter brushes 88, 5 segment 81, to all of the 5" segments 81,

brush 88 in the highest order of ACC#4, strip.

88, contacts 99b, now closed due to the energization of magnet R99, wire I81, contacts IMa. wire IOI, to one of the print magnets 31, and through plug connections I88 to other print magnets 81.

Printing will take place in the same manner as explained above in connection with the direct entries from the card and as the tvpe bars are selected for printing. the associated contacts 52 will be closed and new again. if the settin of the type bars is identical in the three positions .in which the tax is printed, the same entering will be illuminated to call the discrepancy to the The previous ener-.

attention of the operator. gization of magnet R99 has closed a pair of contacts R99e (Fig. 8) completing a circuit from line II I, cam contacts LIE, contacts R990. relay magnet R52, wire I2I, to line -II3. Contacts R521) provide a holding circuit which runs through cam contacts P8 so that the magnet R52 will 'remain energized until total printing operations have been performed. A second pair of contacts R52a will be opened upon energization of magnet R52 thereby interrupting the holding circuit through the tax pickup relay magnets R46 and R41 which in turn will now permit opening of contacts R41a and closure of contacts R41b so that relay magnet R99 can now be deenergized when cam contacts Ll1 open.

Arrears tax cycZe.Near the end of the tax transfer cycle, cam contacts LI3 will again close, this time comp eting a circuit from line I I I, contacts,LI3, contacts R55b or R44a as the case may be, contacts R4111, contacts R45b. closed as explained above, relay magnet RIM, wire I2I, to line 'I I3.

Magnet RIM will close itscontacts RlMd to provide a holding circuit for itself through cam contacts LI1 and P8 and a pair of contacts RIMe will-close to energize relay magnet RSI when cam contacts LI8 close later.

In Fig. 8b. relay magnet RIM will close its contacts RIMb so that transferring during this cycle may take place from ACC#5 to the type bars 31. Such transferring circuit is traceable from the read-out strip 88 of ACC#5, through contacts RiMb, wire I IN, to the print magnets 31 and again as in the case of the tax amount, if the type bars are all positioned alike. the entry will be made into ACC#I and lamp I29 illuminated if there is any discrepancy.

After this transferring of the arrears amount has been effected, cam contacts LI1 open so that magnet RIM will be deenergized and its various contacts will return to the positions shown in the circuit.

Entering the merchandise am'ount.If the group of cards contains a merchandise cardfollowing the service cards, the machine will enter upon one or more card feeding cycles during which the merchanidse amount will be printed and entered into ACC#|. Resumption of card feeding is brought about as follows:

When both relay magnets R99 and RI00 are deenergized their related contacts R99g and Rl00g will be closed and the circuit through relay magnet R39 re-established so that in turn contacts R39b will be closed to energize the card feed clutch magnet I8 and the merchandise card will proceed past the lower brushes which will complete the printing and entering circuits in the same manner as explained in connection with the entry of data from the gross and net bill fields. It is in these same fields that the merchandise amount is perforated.

Total printing and reset cycle The circuit through relay magnet R39 includes the minor control relay magnet contacts R430 and R43d which upon detection of a group number change by the automatic group control mechanism GC will interrupt further card feeding and automatically initiate total taking and resetting operations. Opening of contacts R43c will interrupt card feeding in thenow familiar manner and closure of contacts R43d will complete a circuit from line III, wire II2, contacts P9, R99g, Ri00g, R43d, cam contacts LI9, relay magnets 30 R and R49 to line H3. The contacts R40a of relay magnet R40 are in the reset magnet circuit and upon closure will cause energization of this;

magnet through a circuit extending from line II3, reset magnet 81, contacts R40a, cam contacts L2, wire II2, to line III. Through the mechanism controlled by magnet 8|, theshaft carrying the cams for controlling the P contacts will function. The first operation to take place will be printing of the total standing in ACC#I. This is brought about as follows: A pair of contacts R40b in the upper part of Fig. 8a will close to complete a circuit extending from line 3 (Fig. 8) contacts R431), wire I40 (Fig. 8a), contacts R40b. relay magnet R98, cam contacts LI8, wire I (Fig. 8), cam contacts LII and P0, to line III. Energization of magnet R98 will close its contacts R98?) in the lower part of Fig. 8a and open its contacts R98a so that the emitter brushes 86 will establish circuits from the read-out strips 68 of ACC#I, through contacts R98b, wire I06, contacts R99a and RI00a, now closed. wire IN, to the print magnets 31. Once -more the checking contacts 52 will determine whether printing is correctly eflected in the several portions of the bill. I

Relay magnet RI02 in parallel with magnet R98 will cause closure of its contactsRI02a in the lower part of Fig. 8a and opening of its contacts Rl02b so that the entering circuits extending from contacts 32 through wires I23 will extend to the adding magnet 50 of ACC#2 instead of to the adding magnets of ACC#I as before.

In this manner, the entry in ACC#I is printed on the bill and through the checking contacts 52 to the route total ACC#2. Later in the reset cycle, the resetting instrumentalities will come into play to zeroize the several accumulators in the manner explained above. In connection with ACC#2, however, the resetting mechanism is ineffective and the amounts in this accumulator will continue to accumulate to obtain a grand total of all the entries transferred from ACC#I.

Automatic resumption of card feeding Cam contacts L3 (Fig. 8) are provided to energize the start relay magnets R32 and R33 near the end of the resetting cycle of operations to pick up and energize the card feed clutch magnet I8. The circuits involved in the starting of the machine have already been traced in detail and the operations controlled thereby will proceed in the same manner as explained above.

If it is'desired to have the machine stop after the completion of the resetting operation, switch I30 (Fig. 8) is initially set in its dotted line position and near the end of the resetting cycle cam .contacts P5 close momentarily to complete a circuit through the relay magnets R31 and R39, the former of which provides a holding circuit through contacts R3Ia and cam contacts L4.

The relay magnet R38 opens its contacts R30a in the upper part of Fig. 8 to prevent the reestablishment of the starting circuit and the machine will consequently come to rest at the completion of the resetting cycle of operations and resumption of operations may then proceed through initiation of the start key to close contacts H9. As explained above, the failure of the type bars to record identical information in the several portions of the bill will efiect energization of relay magnets R35 and R38 and will illuminate lamp I29 and with switch I30 in its full line position during the total taking operation closure of cam contacts P5 will complete a circuit from line H3, through relay magnets R38, R31, contacts P5, switch I30, contacts R3Ia, R3312, wire 2, to line III. As just stated energization oi relay magnets R31 and R38 will cause the machine to stop at the completion of resetting and the continued illumination of lamp I29 will indicate to the operator that the stopping of the machine has been occasioned by a discrepancy in printing in one or more lines of the bill. Major total stop The machine is arranged to automatically stop upon a major group change; that is, when all record cards having the same group number in columns 9 to 12 have passed through the machine. In such event, the group control mechanism GC will cause deenergization of the major control relay magnet R42 permitting closure of its contacts R420 which will establish a circuit from line H3, contacts R42a. wire I45, in parallel through lamp I46 and relay magnet R4I, cam contacts LI9, contacts R43d, RI00a, R99 7, cam contacts P9, wire II2, to line I II.

Relay magnet R4I opens its contacts R4Ia in the starting circuit, preventing the completion of the same. The machine will come to rest with lamp I48 illuminated. It will thus be apparent that the machine will automatically come to a stop under two conditions. First, when there has been a discrepancy in printing, and second, when there has been a major group change. In order to indicate under which of these conditions the machine has come to rest, the lamps I29 and I48 are provided, for former indicating by its illumination that the stopping .7

is due to a. printing discrepancy, and the latter, that the cards relating to a particular route have all been analyzed.

All

an X22 perforation but none contains an K perforation, only the tax transfer relay circuits controlled by relay magnet R" will be energized so that upon the operation of the group control mechanism or the analysis'oi the inerchandise card, the machine will proceed. through the tax printing and transferring cycle of operations as described above. At the completion of this transfer cycle, since the arrears pick-up magnet R45 was not energized during the analysis of the group, its contacts R4512 will be opened, the arrears transfer magnet RIM will not be energized, and consequently both contacts Rlllt g and R99g will be closed at the end of the tar; transfer cycle so that the total taking and resetting cycle or merchandise feed cycle will be initiated at this time as explained.

If a card of the group contained an X80 perforation but no X22 perforation, then only the arrears pick-up relay magnet R45 would be energized andnot the tax pick-up relay magnet RH, so that upon the initiation of transferring operations, magnet RIM will be energized instead of magnet R99 due to the fact that contacts R41 will open and contacts R412) and R45b close.

At the completion of the transfer cycle, during which the arrears amount ortotal in ACCikEi is transferred to ACC#I, magnet Rlllll will he deenergized and again contacts Rlllllg and Rllllg are closed at the end of the cycle so that total taking and resetting cycles or merchandise feed cycle will'immediately follow.

Where none of the cards of the group contain either the X22 or X80 perforation, indicating that no transferring operations are to take place for that group, contacts Rlllilg and Rlldg will both he closed at the end of the last card feeding cycle so that closure of contacts Lil] near the end of that cycle will initiate the totm taking and resetting operations without intervening transferring cycles,
